(1) Get rid of "nox11" -- the concept of "no" in package options is
expressed by negating an option; use "-x11" instead.
(2) Teach editors/emacs20 to use package options instead of EMACS_USE_POP,
EMACS_USE_X, EMACS_USE_X_TOOLKIT and USE_INET6. We now use similar
options as the other emacs packages, i.e. "x11", "motif", "xaw",
as well as "pop" and "inet6".
(3) Make the emacs*-nox11 packages simply remove all X11 options by
setting PKG_OPTIONS.emacs appropriately and include the corresponding
emacs Makefile. This allows for modifications to the emacs "X11"
versions to be automatically picked up by the "non-X11" versions.
The two corresponding versions of emacs now share the same version
numbering, including PKGREVISIONs.
Bump the PKGREVISIONs on all Emacs editor packages.
<uebayasi@soum.co.jp>:
-select a reasonable set of options instead of using a ton of
/etc/mk.conf variables
-dtrt with dependencies
-USE_BUILDLINK_ONLY
-use INSTALL_SCRIPT instead of creating a mess
derived from our emacs-20.7 pkg; IPv6 and newer NetBSD platform/toolchain
support appear to be included in the original sources, so I've only
left in the patches which deal with info file installation and the "emacs-"
prefix for user tools
